| Watch a baby between six and nine
months old, and you will observe the basic concepts of geometry being learned.
Once the baby has mastered the idea that space is three-dimensional, it reaches
out and begins grasping various kinds of objects. It is then, from perhaps nine
to fifteen months, that the concepts of sets and numbers are formed. So far, so
good. But now an ominous development takes place. The nerve fibers in the brain
insulate themselves in such a way that the baby begins to hear sounds very
precisely. Soon it picks up language, and it is then brought into direct
communication with adults. From this point on, it is usually downhill all the
way for mathematics, because the child now becomes exposed to all the nonsense
words and beliefs of the community into which it has been so unfortunate as to
have been born. Nature, havin A. indifferent B. compromising C. indulgent D. cynical [判断题] 若使用的滑车可能着地，则应在滑车底下垫以木板，防止垃圾窜入滑车。( ) A.正确，B.错误。

[单项选择]A recent history of the Chicago meat-packing industry and its workers examines how the industry grew from its appearance in the 1830’s through the early 1890’s. Meat-packers, the author argues, had good wages, working conditions, and prospects for advancement within the packinghouses, and did not cooperate with labor agitators since labor relations were so harmonious. Because the history maintains that conditions were above standard for the era, the frequency of labor disputes, especially in the mid-1880’s, is not accounted for. The work ignores the fact that the 1880’s were crucial years in American labor history, and that the packinghouse workers! efforts were part of the national movement for labor reform.
In fact, other historical sources for the late nineteenth century record deteriorating housing and high disease and infant mortality rates in the industrial community, due to low wages and unhealthy working conditions. Additional date from the University of Chicago suggest th A. inform the reader of events that occurred in the meat-packing industry after the period of time covered by the history B. suggest the history’s limitations by pointing out a situation that the history failed to explam adequately C. salvage the history’s point of view by suggesting that there were positive developments in the meat-packing industry due to worker unity D. introduce a new issue designed to elaborate on the good relationship between the meat-packers and Chicago’s ethnic communities [多选题]作品朗读训练中，朗读的要求是(____)。
